Overview: Surgical site infection (SSI) is a leading cause of postoperative complication, rehospitalisation, and patient mortality after invasive clinical interventions. Surgical risks compounded by SSI introduce greater medical, economic, and quality-of-life challenges for both patients and providers alike, and to better inform clinical practice, empirical evaluation of modern surgical warming techniques is relevant. This systematic review and meta-analysis qualitatively examined the efficacy of both active and passive perioperative warming interventions upon SSI presentation versus standardised (i.e., non-warming) care. Methods: This review analysed available literature on active and passive warming application across general anaesthesia procedures, containing longitudinal data on patient outcomes and SSI. The primary outcome studied was occurrence of post-surgical SSI; secondary outcomes included rehabilitative length of stay, attributable SSI-related mortality, and incidence of re-admittance. Results: Meta-analysis demonstrated a significantly reduced risk ratio for SSI in patients receiving any surgical warming intervention (odds ratio: 0.36; 95% confidence interval: 0.18–0.87; p |
